Yes Pyro ... where flaps were a saviour before, they are now instant death.
Are you flying it with CT or manual trim ?

I too find myself struggling desperately to keep some speed when maneuvering, hearing the stall buzzer the instant I move the stick, and having those incredibly nasty departures when stalling, even at relatively high speeds and when nose down. It really seems to bleed speed way too fast and accelerate poorly when manuevering. When you get to 200 or so, any stick movement gives you a blaring stall horn. And you never get the speed back anywhere near as fast as you did, even nose down in WEP.
I experience all of this too. Nose down trim, pulling into a turn at 300 mph will set the stall horn off without much of a pull. If I trim nose up, speed drops drastically and it becomes very unstable and very hard to regain speed.
